Beschreibung
Zusammenfassung:	Process for the coating of polymer particles, comprising contacting the particles with a composition comprising an additive, a film-forming binder that is miscible with the polymer, and a distributing agent, removing the distributing agent at a particle temperature at which the binder can form a film and that is below the softening temperature Tp of the polymer, and forming and consolidating an additive-containing layer of binder on the polymer particles, the polymer particles being kept in mutual motion while they are being contacted with the composition and while the additive-containing layer of binder is being formed and consolidated.
